LOCK FOR STOP-COCKS.

SPECIFICATION forming part of LettersPatent No. 566,932, dated September 1, 1896.

Application filed November 15, 1895. Serial No. 569,053. (No model.)

To all whom it may concern.-

Be it known that 1, ALBERT T. PATRICK, of New York city, in the county and State of New York, have invented a new and Improved Lock for Stop-Cocks, ofwhich the following is a full, clear, and exact descrip tion.

The object of the invention is to provide a new and improved stop-cock lock which is simple and durable in construction, easily applied or removed, and more especially designed for temporarily or permanently locking the turn-key of an ordinary stop-cock.

The invention consists principally of a slotted hasp adapt-ed to be passed around thestop-cock and engage with its slot the turnkey of the cock, the free ends of the hasp being adapted to be locked together.

The invention also consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings,forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement as applied. Fig. 2 is an end elevation of the same, and Fig. 3 is a like view of a modified form of the hasp.

The improved stop-cock lock is provided with a hasp A, either made of a single piece of metal, as shown in Fig. 3, or with two members A and A hinged together, as at A as seen that when the hasp is placed around the stop-cock body and engages the slots therein with theturn-key B and the free ends of said hasp are fastened together then it is impossible to turn the turn-key B and open the stop-cock. It will be seen that this device can be conveniently and readily applied on an ordinary stop-cock at the time the latter is in a closed position, and thus lock the turn-key and prevent unauthorized persons from opening the cock. It is expressly understood that this lock in not a permanent part of the stop-cock. It isalso understood that when the hasp A is made of a single piece of spring metal, as shown in Fig. 3, then the sides can be sufficiently bent apart to readily slip the hasp upon the cock and to engage the turn-key B for locking the same in place, as previously explained.

The device is especially serviceable for use on supply-pipes for houses and other buildings, in case it is desired to cut off the supply without removing the meters or otherwise disturbing the supply-fixtures.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A look of the class described, provided with a slotted hasp adapted to pass around the stop-cock and engage with its slot the turn-key of the cook, the free ends of the hasp being adapted to be locked together, substantially as shown and described.

2. A look of the class described, comprising a hasp having two slotted members hinged together, the slots being adapted to engage the turn-key of the cock, and a locking device for connecting the free ends of the hasp members with each other, substantially'as shown'and described.
